[COMPUTER] [2010] Sci-fi shooter similar to Halo

I don't remember much, but what I do remember:

It was a sci-fi style shooting game, the armor was very similar to Halo (but it's not Halo).

I played Capture the Flag a lot, I remember that it was possible to fly (jump and glide until you fell), “surf” and spawn in respawn ships.

I've searched Google and can't find it. I don't think it was very well known. It was a computer game.
